Answer 2

To evaluate the expression when a = 10 and c = 16, we substitute these values into the given expression and simplify it.

The expression is:

5a/4c - 25a^2 + 16c/20ac + 4c - 25a/5a

Substituting a = 10 and c = 16:

5(10)/(4(16)) - 25(10)^2 + 16(16)/(20(10)(16)) + 4(16) - 25(10)/(5(10))

Simplifying further:

50/64 - 2500 + 256/3200 + 64 - 250/50

Now, let's calculate each part of the expression:

50/64 = 0.78125

2500 - This term doesn't require any further calculation.

256/3200 = 0.08

64 - This term doesn't require any further calculation.

250/50 = 5

Now, we substitute the calculated values back into the expression:

0.78125 - 2500 + 0.08 + 64 - 5

Calculating further:

-2499.11875

Therefore, when a = 10 and c = 16, the given expression evaluates to approximately -2499.11875.
